A car moves with an average speed of 45miles /hour. How long does the car take to travel 90miles?
storchak [24]

Averqge speed of the car = 45 miles/hr, which means,

The car travels 45 miles in 1 hr.

Using unitary method,

The car travels 45 miles in 1 hr

The car would travel 1 mile in 1/45 hrs

The car would travel 90 miles in 1/45×90 hrs

So, calculating this,

1/45×90 = 2 hrs
