Answer:
Total distance travelled in 2 hours is 8kilometres.
Step-by-step explanation:
First, you have to find the speed of the boat that travel 20km for 5hr. Using the formula, speed = distance/time :
S = D/T
D = 20km
T = 5 hours
S = 20/5
= 4km/hr
We know that the boat travel at a constant speed during the tour so niw, we have to find the distance travelled during first 2 hours. Using the formula, D = S×T :
S = 4km/hr
T = 2hr
D = 4×2
= 8km
Answer:
If the boat is traveling at a constant speed for 5 hours and goes 20 kilometers, the boat would have been going 4 kilometers/hour.
Now you can take the kilometers/hour and multiply by 2 to see the distance traveled in 2 hours.
5 ÷ 20 = 4
4 × 2 = 8
The distance traveled in two hours is 8 kilometers.
