Question

A SCOOTERIST TRAVELS AT 30 km/h ALONG THE STRAIGHT PATH FOR 20 min. HOW MUCH DISTANCE HAS HE TRAVELLED?

Answer 1

Task. A scooterist travels at $v=30$ km/h along the straight path for $t=20$ min. How much distance has he travelled?

Solution. The distance travelled by scooterist is equal to

$d=vt.$

Substituting its velocity

$v=30~{}km/h$

and time

$t=20~{}\text{min}=\frac{1}{3}~{}\text{hours}$

we get

$d=30*\frac{1}{3}=10~{}\text{km}.$

Answer. 10 km.
