Question

If the speed of a motorcycle is 40 km per hour, how far will it travel in an hour and a quarter?

Answer 1

Hour and quarter = `1 + 1/4` hours

= 40 km + `1/4 xx 40` km

= 40 km + 10 km

= 50 km

∴ Motorcycle will travel in a hour and a quarter 50 km.

Answer 2

Given:

The speed of a motorcycle is 40 km per hour.

Solution:

The hour and a quarter means 1 + `1/4`

1 hour = 40 km

And `1/4 = 40 xx 1/4 = 10` km

`1 + 1/4 = 40` km + 10 km

`1 +1/4` = 50 km

So, 50 km travel in an hour and a quarter.
