Answer:
31.46 km/hr to the nearest 100th
Step-by-step explanation:
10:55 to 11:00 is 5 min
11:00 to 12:00 is 60 min
12:00 to 12:38 is 38 min
That's 5 + 60 + 38 = 103 min = 103/60 hr. = t
d = rt
54 = 103/60(r)
r = 54(60)/103 =31.46 km/hr to the nearest 100th
Janet = 7.55 x 15(hours) = 113.25
Kelsey = 15.10 x 15(hours) = 226.50
Ty = 13.85 x 15(hours) = 207.76
To gets Kelsey’s wage per hour you do 7.55 x 2 and to get ty you do 15.10(Kelsey’s wage per hour) - 1.25 which is 207.76

Answer:
4 hours and 30 minutes.
Step-by-step explanation:
660 miles = 1 hour
1320 miles = 2 hours
1980 miles = 3 hours
2640 miles = 4 hours
There are only 330 miles left and that is half of 660mph so therefore it would only take half an hour for these last 330 miles.
So we know that it will be taking 4 hours, you would then add the 30 minutes which gives you 4 hours and 30 minutes.
Hope this helps!
