Tory and Emilio's motorboats travel at the same speed. Tory pilots her boat 40 km before docking. Emilio continues for another 4 hr, traveling a total of 90 km before docking. How long did it take Tory to navigate the 40 km?
I need help with this kinda of math
To find out how long it took Tory to navigate the 40 km, we need to determine the speed at which the motorboats are traveling.
Since Tory and Emilio's motorboats travel at the same speed, we can calculate the speed by dividing the total distance traveled by Emilio in 4 hours (90 km) by the time it took him (4 hours).
So, the speed at which the motorboats are traveling is 90 km / 4 hours = 22.5 km/h.
Now that we have the speed, we can calculate the time it took Tory to navigate the 40 km by dividing the distance by the speed:
Time = Distance / Speed
Time = 40 km / 22.5 km/h
Time ≈ 1.78 hours
Therefore, it took Tory approximately 1.78 hours to navigate the 40 km.
