Question

A car drives at a speed of 90 km/h for 2 hours and 20 minutes
How far does the car drive?

Answer 1

210kms

Explanation:

Speed of the car per hour = 90km/h

or, speed of the car per minute = 90/60kms=1.5km/minute

Now,

car drives for 2hours and 20 minutes

or, (2*60 +20) minutes= 140minutes

Distance of the car drive= minutes travelled* speed per minute

= 140*1.5kms

=210kms

Answer 2

210km

Explanation:

2hours = 180km

2hours = 120minutes

40mins =180/3

=60km

20mins=60/2

=30km

2h and 20mins =30+180

=210km
