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
If that's the whole question then what exactly are we trying to solve here?
3/8 cups
Total fraction = 1/4 + 1/8
= 2/8 + 1/8
= 3/8
