The equation in terms of x, for the total time he takes in hours would be 2.48 = 12/x + 26/10x
<h3>What is speed?</h3>
Speed can be calculated as the ratio of distance traveled to the time taken
Darpan runs a distance of 12 km and then cycles a distance of 26 km.
Total distance = 12 + 26 = 38km
The running speed is x km/h
A = x
The cycling speed is 10 km/h faster than his running speed
B = 10x
He takes a total time of 2 hours and 48 minutes.
So, the total time he takes
Time = Distance x speed
2.48 = 12/x + 26/10x
10x(2.48) = 120 + 26
24.8x = 146
x = 5.8

Answer:
as x -> -∞, y-> ∞ and as x-> ∞, y -> -∞ - <u>Second option</u>
Step-by-step explanation:
If you look carefully to the left, when x becomes negative the y value becomes positive. On the right, x becomes positive and y becomes negative.

Step-by-step explanation:
He rowed 31.5 miles in half of an hour, to get speed per hour, you multiply by two.
31.5*2=63
Doug's average speed is 63 miles per hour~_~
