Answer: 1130km
Step-by-step explanation:
Initial Time taken by boat = 7 hours
Initial speed of boat = 80 km/h
New speed of boat = 95 km/h
New time taken by boat = 6 hours
Total distance sailed by boat = ?
Recall that speed is the total distance travelled divided by the total time taken.
i.e Speed = distance / Time taken
Distance = speed x time taken
So, from the data provided we will calculate the distance travelled in under the two conditions
In 1st case: distance = 80 km/h x 7 hours
distance = 560 km
In 2nd case: distance = 95km/h x 6hours
distance = 570 km
Hence, total distance = 560km + 570km
= 1130km
Thus, the boat had sailed 1130 kilometers far
