step by step explation plls
Answers
Answer:
Time taken to travel from A to B excluding stops can be found using the formula: time=
Speed
Distance
On solving, t
t
=
70
175
hr
t
t
=
70
175
×60 min
t
t
=150 min
Now, stop time at first signal is t
1
=1 s
at second signal is t
2
=3 s and so on
This forms an arithmetic progression with first term a
1
=1, common difference d=2, number of terms n=10
Total stop time is the sum of this series. Hence,
t
s
=
2
n
(2a
1
+(n−1)d)
t
s
=
2
10
(2×1+(10−1)×2)
t
s
=100 min
Total travel time equals the sum of stop time and travel time.
t=t
s
+t
t
t=100+150
t=250 min=4 hr 10 min
Answer:
distance -175m
time-1 min
Then speed =distance/ time
175m/1min
175m/min
U can change the speed in km/h .
1m/min=0.06km/h
175m/min=175×0.06 km/h
=10.5 km/h
hope it'll helpful for u .
