Every morning, Jim goes for a morning walk. His normal walking speed is 3 1/2 km per hour, and he walks a total distance of 10 km every day. How much time does he take to cover one km? Hint 1 Notice the unit of Speed.

Hint 2 Can you figure out the distance covered in one hour​

Jim's walking speed = 312kmph

covered distance = 10km

time taken for one hour = ?

we know that: Distance =speed × time

=>Time = Distance/speed

=> Time = 10/312=5/156 hours

= Time = (5×60)/156=300/156=75/39=1.9 minutes

Step-by-step explanation:

the answer is c hope it

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
