Question

A cycliest rides at 30 kilometers per hour. how far will travel in 21/2 hours

Answer 1

• Speed=30km/h
• Time=21/2=10.5h

`\\ \tt\hookrightarrow Speed=Distance/Time`

`\\ \tt\hookrightarrow Distance=Speed* Time`

`\\ \tt\hookrightarrow Distance=30(10.5)`

`\\ \tt\hookrightarrow Distance=315km`

Answer 2

• 315 kilometers.

Explanation:

We know that:

• 30 kilometers = 1 hour

Solution:

• 30 kilometers = 1 hour
• => 30 x 21/2 kilometers = 21/2 hours
• => 15 x 21 kilometers = 21/2 hours
• => 315 kilometers = 21/2 hours

Hence, in 21/2 hours, the cyclist rides 315 kilometers.
