Question

A car travels 35km north in 25m then 35km south in 35m what is the average speed?​

Answer 1

Answer:

70km/h

Explanation:

=Total distance/Total time

Total distance =35km+35km=70km

Total time =35 min + 25 min= 60 min/60= 1 hour

Speed = dist/time=70/1

=70km/h

If they ask for velocity though it will be zero because there is zero displacement

Answer 2

Answer:

• 70 km/hr.

Step-by-step explanation:

Question -

A car travels 35km north in 25m then 35km south in 35m what is the average speed?

ㅤ

Given-

• Distance in 25mins = 35 km.
• Distance in 35 mins = 35 km.

ㅤ

To Find -

• Average Speed.

ㅤ

Solution-

Let's first calculate total distance and time.

ㅤ

$\purple\bigstar$ Total distance = 35+35= 70 km.

$\pink\bigstar$ Total time = 25 +35 = 60 mins = 1 hr.

ㅤ

Average Speed = $\frac\red{total\:distance}\red{total\:time}\\ \\=\frac{70}{1}\\ \\=\sf\blue{70km/hr}$

So, average speed is 70 km/hr.
