Question

16. A man walks at 6 km/h and runs at 8 km/h. He covers 6 km in 50 min partly by running
and partly by walking.
(i) For how long did he walk? (ii) What distance did he cover walking?​

Answer 1

Step-by-step explanation:

Answer. Thus, The distance he covers in walking = 2 km, And, the distance he covers in running = 6 - 2 = 4 km.

Answer 2

Step-by-step explanation:

let he walk x km so run 6-x km

we know that his speed in walk as well as run

time=distance/speed

so total time =50min

x/6+(x6-x)/8= 5/6 (because 50min =5/6 hours)

(4x+18-3x)/24=5/6

x+18=5*4

x=2km

so 6-x=4km

total walk 2km

and total run 4km
