Answer:
1846= 0% change
1847= 3.2/5 ×100 = 64% decrease in river
1848= 6.8/3.2 ×100 = 212.5% increase
( used 3.2 because that was the last record)
Let speed of car be x mph
At 1pm, cargo is 26 mph * 1 hour = 26 miles away from intersection.
At 1pm, car is x mph*30 minutes = x/2 miles from intersection.
Since it is given they travel in opposite directions, and are 51 miles apart, we have
26+x/2=51
Solve for x
x/2=51-26=25 mph
x=25*2=50 mph.
Car was travelling at 50 mph
