First let's find how many hours it will take to get there.
270/45 = 6
It will take 6 hours to get there.
6 hours past 1:30 is 7:30.
The answer is 7:30 p.m.
Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)
Average speed =
(total distance covered) / (time to cover the distance).
Total distance covered = (58km + 80km) = 138 km
Time to cover the distance = (4hr + 4hr) = 8 hours
Average speed = 138km / 8hr = 17.25 km/hour .
(That's less than 11 mph. You could bike there faster!)
A calculator fitting the data with an exponential model shows the annual multiplier is approximately 1.0367.
The effective annual interest rate is 3.67%.
If you are asking for the one with the highest degree polynomial it would be -4x^10 because the power is the highest.
