1. Rhea takes 20 minutes from her house to reach her school on a bicycle. If the bicycle has a speed of 2 ms-1. Calculate the distance between her house and the school.

2. How much distance is travelled by an object if it travels at a constant speed of 60 Km/h for 2 hrs?

Answer 1

Answer:

MARK me as brainlist.

Step-by-step explanation:

speed= 60 km/h

time=3 hrs.

distance= 60*2= 120 km.

Answer 2

We know that :

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

hence distance = speed × time

$distance = 20 \times {2ms}^{ - 1}$

distance = 40m

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

60km/h into m/s : 50/3 m/s

$\frac{50}{3} = \frac{x}{120}$

120 × 50 = 3x

6000 = 3x

$\frac{6000}{3} = x$

2000 m = distance

2km = distance

hope it helps

have a great day
