Pam jogged up the hill at 6 km/h and then jog down back down the hill at 10 km an hour how many kilometers did you travel at all if she told Ryan jogging time is an hour and 20 minutes

Answer: you travelled 10 km

Step-by-step explanation:

Pam jogged up the hill at 6 km/h.

Let x represent the number of kilometers that you travelled by jogging up the hill or returning back.

Time = Distance/speed

Pam jogged up the hill at 6 km/h.

Time spent in jogging up the hill would be

x / 6

She then jog back down the hill at 10 km an hour. Time spent in jogging down the hill would be

x / 10

If the total jogging tie is 1 hour 20 minutes, converting to hours, it becomes 1 + 20/60 = 1.33

Therefore

x / 6 + x/10 = 1.33

10x + 6x = 80

16x = 80

x = 80/16 = 5

Total distance travelled up and down the hill would b

5 * 2 = 10 km
