Question

Samuel walks for $7\frac{4}{2}$ minutes. He took taxi for $3\frac{5}{2}$ minutes to reach the School. Calculate the time taken to reach the School?

• A. $\frac{29}{2}$
• B. $\frac{39}{2}$
• C. $\frac{2}{29}$

Answer 1

The correct option is A $\frac{29}{2}$

Time taken for walking $=7\frac{4}{2}$ minutes
Time spent in taxi $=3\frac{5}{2}$ minutes
Total time taken to reach the school = Time taken for walking + Time spent in taxi
$=7\frac{4}{2}+3\frac{5}{2}$
Add the whole numbers $=7+3=10$
Add the fraction part$=\frac{4}{2}+\frac{5}{2}=\frac{4+5}{2}=\frac{9}{2}$

Now, combine both the whole number and the fractional part as follows,
$\therefore 7\frac{4}{2}+3\frac{5}{2}=10\frac{9}{2}$

Now, convert the mixed number into an improper fraction
$10\frac{9}{2}=\frac{10\times 2+9}{2}$
$=\frac{29}{2}$

$\therefore$ Total time taken to reach the school is $\frac{29}{2}$ minutes.
