Question

2. Find the Time, when
(1) Distance = 100km, Speed = 20 km/hour
(ii) Distance = 500km, Speed = 10 metre/second​

Answer 1

Answer:

speed= distance/time

so

(I) time = 100/20=5 hr

(ii) time = (500km)/{(10*(60*60/1000)}

= 500*1000/(10*60*60)=13.89 hr

Answer 2

Answer:

1. 5hr

2. 13.89 hr

Step-by-step explanation:

distance = Speed × time

therefore, time = distance / Speed

1. 100/20 = 5

2. 500/36 = 13.89. (1 m/s = 3.6 km/hr)
