Question

A car can travel 60 km in 45 minutes. What is the distance the car can travel in 1 hour at the same speed?

Answer 1

Distance = 60 km.
Time = 45 minutes = 0.75 hours.
Speed = 60/0.75.
= 80 km/h.

Time = 1 hour.
Distance = Speed*Time.
= 80*1.
= 80 km.

$therefore \: the \: car \: travels \: 80 \: km \: in \: 1 \: hour.$

Answer 2

$hey \: friend \: good \: evening \\ heres \: ur \: answer$
$distance \: that \: car \: travels \\ in \: 45 \: mins = 60km \\ \\ \\ 45mins \: time \: in \: hours \\ = \binom{45}{60} = 0.75hrs$
$as \: we \: know \: that \: speed = \\ \binom{distance}{time} \\ therefore \: speed \: = \\ \binom{60}{0.75} = 80km perhr$
Now, in a time of 1 hour = 60 mins.
Distance that car can travel at a speed of 80km/hr
$= 80 \times 1 = \\ 80kmperhour$
