Question

How many hours in 90 minutes?

A. 1.5 hours
B. 1.30 hours
C. 1 hour
D. None of these.

Answer 1

1.5 hours

Explanation:

We know that:

1 hour = 60 minutes

Then

90 minutes = 60 minutes + 30 minutes

Since 60 minutes is an hour, then 30 minutes is half an hour; 90 minutes = 1.5 hours.

Answer 2

A. 1.5 hours

Explanation:

1 hour = 60 minutes

90min x
`(1 hour)/(60 min)`

90/60 hours

90/60=1.5 hours
