Question

A car travels 90 km in 2 hr 30 min.
Find the distance covered in 2 hrs with the same speed.​

Answer 1

Answer:

Distance = 90 kilometres

Time = 2 hours 30 minutes

And Speed = distance / time

Therefore, Speed = 90/2.5 = 36 kmph

Now we know the speed so,

Speed = Distance / Time

36 = Distance / 2

Distance = 72km

Answer 2

Answer:

D1= 90 km T1= 2hr 30mins= 150 mins

D2= ?? T2= 120 mins

D1 = T1

D2= T2

Therefore D2= 90 × 120 / 150

= 1080/15

= 72 kms
