Question

Convert the following into hours :
(a) 240 min.=
(b) 300 min. =
(c) 600 min.=
(d) 720 min.=
(e) 900 min.=
(0) 1200 min.=​

Answer 1

1 minute = 1/60 hours

(a) 240 min = 1/60 × 240 = 4 hours

(b) 300 min = 1/60 × 300 = 5 hours

(c) 600 min = 1/60 × 600 = 10 hours

(d) 720 min = 1/60 × 720 = 12 hours

(e) 900 min = 1/60 × 900 = 15 hours

(0) 1200 min = 1/60 × 1200 = 20 hours

this is the answer of this question.

Answer 2

${\huge{\underline{\underline{\rm{Answer\checkmark}}}}}$

$\star \rm \: 1hour \longrightarrow \: 60 \: minutes \\ \\ \star \rm \: 1 \: minute \: \longrightarrow\: \frac{1}{60} hours$

$\rm (a) \: 240 \: min\mapsto \: \frac{1}{60} \times 240 = 4 \: hours$

$\rm (b) \: 300 \: min \: \mapsto \frac{1}{60} \times 300 = 5 \: hours$

$\rm(c) \: 600 \: min \: \mapsto \: \frac{1}{60} \times 600 = 10 \: hours$

$\rm(d) \: 720 \: min \: \mapsto \: \frac{1}{60} \times 720 = 12 \: hours$

$\rm(e) \: 900 \: min \mapsto \: \frac{1}{60} \times 900 = 15 \: hours$

$\rm(f) \: 1200 \: min \: \mapsto \: \frac{1}{60} \times 1200 = 20 \: hours$
