7. A bus travels 90 km in 2 hours. How long will it travel in 3 hours 30 minutes at the same
speed ?
​

Answer 1

Answer:

There are 60 mins in 1 hour. So 2.5 hours gives us 150 minutes. The car travels 90kms in 150mins. We know that one third of 90kms is 30mins. So the time required by the car to travel 30kms will be one third of 150mins which comes out to be 50mins. Or you can try this method-

90kms in 150mins

30kms in x mins

x= (150 X 30)/90=50 mins

Answer 2

$\huge{\underline{\underline{ \rm{QUESTION}}}}$

A bus travels 90 km in 2 hours. How long will it travel in 3 hours 30 minutes at the same

speed ?

$\: \: \:$

$\huge{\underline{\underline{ \rm{ANSWER}}}}$

$\: \: \:$

Distance travelled in 2 hours = 90 km

Distance travelled in 1 hour = Distance ÷ Time = $\frac{90}{2} = 45$

$\: \: \: \:$

Distance travelled in 3.5 hours = Speed × Time = 157.5 km

Hence, the bus travels 157.5 km in 3 hours and 30 minutes to with same speed.
