Question

A car is moving at a uniform speed of 90 km/h.
(a) How far will it travel in 40 minutes?
(b) In how much time will it travel 30 km?
pls answer both parts of it​

Answer 1

Step-by-step explanation:

Given:

• Car is moving at a uniform speed (S) = 90 km/h
• (a) time(t) = 40 mins
• (b) Distance (D) = 30 km

To find:

• (a) Distance in 40 min = ?
• (b) Time (t) for traveling 30 km = ?

Solution:

(a) We are given with the

speed = 90 km/h,

time = 40 min, and we have to find the distance.

We know, $speed \: = \: \frac{distance}{time}$

So, $distance \: = \: speed \: \times \: time$

==> Distance = 90 × 40

Hence, Distance = 3600 km

(b) We are given with the

Speed = 90 km/h,

Distance = 30 km, and we have to find the time.

$speed \: = \: \frac{distance}{time}$

So, $time \: = \: \frac{distance}{speed}$

$= = > \: time \: = \: \frac{30}{90}$

$= = > \: time \: = \: 0.33 \: s$

Hence,time = 0.33 seconds

Hope it helped you dear...
