Question

If one airplane can travel at a maximum speed of 600miles per hour and another airplane at max speed of 720 miles per hour, then how many more miles can the faster airplane travel in 12 seconds than the slower airplane?​

Answer 1

➥Question

• If one airplane can travel at a maximum speed of 600miles per hour and another airplane at max speed of 720 miles per hour, then how many more miles can the faster airplane travel in 12 seconds than the slower airplane?

➥Given

• 2 planes are at the speed of 600 miles per hour and another plane 720 miles per hour.

➥To find

• Distance in miles by the faster airplane to the slower one.

➥Solution

To convert miles per hour to miles per second:-

$\large \rm \blue { 1\:hour\:=60\:×\:60\:seconds }$

Slower airplane speed = 600 miles

$\large \rm \frac{600}{3600} \times 12 \: = \: 2 \: miles$

Faster airplane speed = 720 miles

$\large \rm \frac{720}{3600} \mathrm \times \mathrm 12 \: = \: 2.4 \: \mathrm miles$

$\large \underline\mathrm\orange{Fastest\:plane\:2.4-2=0.4miles}$

Answer 2

Question :-

If one airplane can travel at a maximum speed of 600miles per hour and another airplane at max speed of 720 miles per hour, then how many more miles can the faster airplane travel in 12 seconds than the slower airplane?

To Find :-

Distance in miles by the faster airplane to the slower one.

Required Solution :-

=>First convert miles per hour to miles per second.

=> Slower airplane speed =600 miles per hour

=>

$\frac{600}{3600} \times 12 = 2 \: miles$

=> Faster airplane speed =720 miles per hour

=>

$\frac{720}{3600} \times 12 = 2.4 \: miles$

=>

$The \: faster \: plane \: can \: travel  \: \\ 2.4−2=0.4 \: miles \: farther, \: which \: is \: the \: same \: as  \frac{2}{5}$
