How many seconds are in $7$ hours ?

Question

Verified by Toppr

Answer 1

There are $60$ seconds per minute and $60$ minutes per hour.

Multiplying these will give you the number of seconds per hour.

$\frac{6 0 s e c}{m i n} \times \frac{6 0 m i n}{h r} \Rightarrow \frac{6 0 s e c}{m i n} \times \frac{6 0 m i n}{h r} \Rightarrow \frac{6 0 s e c \times 6 0}{h r} = \frac{3 6 0 0 s e c}{h r}$

We can now multiply this by $7$ hours to find the number of seconds in $7$ hours :

$\frac{3 6 0 0 s e c}{h r} \times 7 h \Rightarrow \frac{3 6 0 0 s e c}{h r} \times 7 h r \Rightarrow 3600 s e c \times 7 \Rightarrow 25200 s e c$

There are $25, 200$ seconds in $7$ hours.

Answer 2

There are

60

seconds per minute and

60

minutes per hour.

Multiplying these will give you the number of seconds per hour.

\frac{6 0 s e c}{m i n} \times \frac{6 0 m i n}{h r} \Rightarrow \frac{6 0 s e c}{m i n} \times \frac{6 0 m i n}{h r} \Rightarrow \frac{6 0 s e c \times 6 0}{h r} = \frac{3 6 0 0 s e c}{h r}

We can now multiply this by

7

hours to find the number of seconds in

7

hours :

\frac{3 6 0 0 s e c}{h r} \times 7 h \Rightarrow \frac{3 6 0 0 s e c}{h r} \times 7 h r \Rightarrow 3600 s e c \times 7 \Rightarrow 25200 s e c

There are

25, 200

seconds in

7

hours.
