Question

Car I covers a distance of 70 km in 60 minutes while another car II covers a distance of 50 km in
50 minutes. What is the ratio of the speed of car 1 and car 2

Answer 1

Answer:

--> 7:5

Explanation:

Given:

• Car I covers 70 km distance 60 min.
• Car I covers 70 km distance 60 min.Car II covers 50 km distance in 50 min.

To find:

• Ratio of their speeds. (Car I : Car II)

Solution:

$ratio \: of \: speeds \: of \: car \: 1 \: and \: car \: 2 \: = > \: \: \frac{car1}{car \: 2}$

$= = > \: \frac{70km}{50km}$

$= = > \: \frac{7}{5}$

Hence, the ratio of their speeds is 7:5.

Hope it helped you dear...

Answer 2

Answer:

Given

car 1

distance covered = 70 km

time taken= 60 minutes = 1 hr

car 2

distance covered= 50 km

time taken= 50 minutes = 5/6 hr

To find

ratio of the speed of car 1 and car 2

Solution

$\bold{✯ speed = distance/ time}$

★speed for car 1

➠speed = 70/ 1

➠speed = 70 km /hr

★speed for car 2

➠speed= 50/5/6

➠speed = 50 x 6/5

➠speed = 60 km hr

❐ Ratio= speed of car 1 /speed of car 2

➠Ratio= 70/60

∴ Ratio = 7/6.
