pls its very urgent​

Answer 1

Given:-

Distance covered by car in 1*1/2 hours=60km.

Find:-

How much distance will it cover in 5 hours?

How much time will it take to cover 75 km?

Solution.

Distance covered by car in 1*1/2 hours or 90 minutes=60km /60000 m.

Distance covered by car in 1 minutes

=60000/90=667m.

Distance covered by car in 5 hours or 300 minutes=300×667=200100 m.

_________________________________________

60 km/60000m distance covered by car =1*1/2hrs or 90 minutes.

1m distance covered by car

=90/60000.

75km or 75000m distance covered by car

=9/6000*75000.

=112.5 or 113 minutes.

=1 hour 53 minutes.

Answer 2

Question :-

A car runs 60km in 1.5 hrs. How much time will it take to cover 75km.

Find :-

Time will it taken by the car to cover 75km.

Solution :-

we know 1 hour = 60 minutes

1.5 hours = 90 minutes

we know 1 km = 1000 m

60 km = 60000 m

a car cover 60000 m in 90 minutes.

${ \bf{So, \: a \: car \: cover \: 1 m = \frac{90}{60000} }}$

75 km = 75000m

${ \bf{So, \: a \: car \: cover \: 75000m}}\\{\bf{= \frac{90}{60000} \times 75000}}$

$= 112.5 \: { \bf{hours \: or}} \: 113 \: { \bf{minutes}}$

${ \bf{= 1 \: hours \: 53 \: minutes}}$
