To find :
speed of Deepa in :
i) km/h
ii) m/s
Given :
distance travelled = 27 km
time taken = 90 min
Formula for calculations:
- speed = distance/time
- km/h = 18/5 × m/s
- m/s = 5/18 × km/h
Solution:
convert the minutes into hours
90 min = 1.5 hours
so, speed of deepa :
i] speed = distance/ time
= 27km/1.5 h
= 18 km/h
ii] m/s = 5/18 × km/h
so, speed of deepa in m/s
= 5/18 × 18
= 5 m/s
